ABOUT THE ULTRALITE-MK3 HYBRID
10
for quick access to all features in one window. Also 
provides full-screen real-time FFT display, 
spectrogram “waterfall” display, oscilloscope, X-Y 
plot and linear or polar phase analysis.
With a variety of I/O formats, mic preamps and 
no-latency mixing and processing of live input, the 
UltraLite-mk3 is a complete, portable “studio in a 
box” when used with a Mac or Windows computer.
THE ULTRALITE-MK3 REAR PANEL
The rear panel has the following connectors:
■
Ten gold-plated, balanced +4dB quarter-inch 
(TRS) analog outputs (with 24-bit 192 kHz 
converters)
■
Six gold-plated, balanced quarter-inch (TRS) 
analog inputs (with 24-bit 192 kHz converters)
■
One combo XLR/TRS mic/instrument input
■
RCA S/PDIF in/out
■
MIDI IN and MIDI OUT jacks
■
One 1394 FireWire A connector
■ One high-speed USB2 connector
■ DC power jack
10 inputs and 14 outputs
All UltraLite-mk3 inputs and outputs can be used 
simultaneously, for a total of 10 inputs and 14 
outputs when operating at sample rates up to 
96 kHz:
All inputs and outputs are discrete and can be 
active simultaneously.
The headphone outputs can operate as an 
independent output pair, or they can mirror any 
other UltraLite-mk3 output pair, such as the main 
outs.
Mic/guitar inputs with preamps
The two mic/instrument inputs (front panel and 
rear panel) are equipped with preamps and 
“combo” XLR/TRS jacks, which accept XLR 
microphone inputs or quarter-inch guitar/
instruments inputs. Individual 48 volt phantom 
power and a 20 dB pad can be supplied 
independently to each mic input. The Precision 
Digital Trim™ knobs on the front panel for each 
mic/instrument input provide 60 dB of boost for 
the XLR mic input and 32 dB of boost for the TRS 
instrument input in precise 1 dB increments.
Analog
All six quarter-inch analog inputs are equipped 
with 24-bit 192 kHz A/D converters. All eight 
analog outputs have 24-bit 192 kHz D/A 
converters. All audio is carried to the computer in a 
24-bit data stream.
All ten analog outputs and six quarter-inch analog 
inputs are on balanced TRS +4dB quarter-inch 
jacks. All of these jacks can also accept unbalanced 
plugs.
Precision Digital Trim™
All of the UltraLite-mk3’s analog inputs are 
equipped with digitally controlled analog trims 
that allow adjustments in 1 dB increments. The 
mic/guitar input trims can be adjusted using front-
panel digital rotary encoders that provide feedback 
in the front panel LCD with 60 dB of adjustment 
for the mic input and 32 dB for the TRS input. All 
analog inputs, including six rear-panel TRS analog 
inputs, can be trimmed using the front panel LCD 
or using the UltraLite-mk3’s included CueMix FX
